The next two episodes – the first of which airs Wednesday, December 4th – will feature Gustin as Barry Allen before he moves into a pilot of his own potential series, The Flash. Hit the jump to watch the promo for “The Scientist”.

Check out the Arrow promo below:

Synopsis:

A seemingly impossible robbery at Queen Consolidated’s Applied Sciences Division brings Central City police scientist Barry Allen (guest star Grant Gustin) to town. Citing a similar case back home, Barry offers to help Oliver (Stephen Amell) and team with the investigation. Oliver senses there is more to Barry than meets the eye, but he’s distracted by the similarities between this current case and something that happened on the island. Meanwhile, Felicity (Emily Bett Rickards) takes a liking to Barry, which doesn’t go unnoticed by Oliver. Sin (guest star Bex Taylor-Klaus) asks Roy (Colton Haynes) for help when a friend of hers goes missing. Roy is surprised when Thea (Willa Holland) not only encourages him to help, but joins the search. Unfortunately, Sin’s friend is connected to Brother Blood (guest star Kevin Alejandro), and their search ultimately gets one of them seriously injured. Michael Schultz directed the episode with story by Greg Berlanti & Andrew Kresiberg and teleplay by Andrew Kreisberg & Geoff Johns (#208).
